This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.
A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

I am new to online learning and to SQL and there is not enough information about how to proceed and complete the course, how to submit assignments and ask questions. To me there is not enough information in the course to complete the quiz and it took looking things up on the internet because much of the information in the quiz/test/assignments is not covered in enough detail to understand and complete the questions without additional research.

If I hadn't already been a little familiar with SQL before this I would have been pretty lost for a lot of this. A lot of the information presented could have used a little more details.
The quizzes often asked questions that involved material that wasn't in the course, as did the coding parts.
At the end of the day, I have had better experiences with some of the free courses available online (and learned more from them).

Good overview of SQL principals but very little practical information.
Tasks don't show correct solution so if you don't know how to solve it - you will never learn it.
Very poor support from admins/moderators. Even questions related to technical issues will stay unanswered. So again - if you didn't understand something from videos or have question outside of the scope - you will not learn it from this course.

The basics were explained adequately, but after that, the explanation often were very abstract and not really practical. I am a visual learner and I like to see pratical examples. The questions in the final exam were sometimes just tedious typing work. Sometimes the gap from what was explained in the video courses what was asked in the questions was a bit too steep.
This course is unbelievably terrible.
First, if we are using SQLite, at least the instructor could show us how to manage or operate SQLite once a while. Secondly, before we go over examples in lecture video, could instructor show ER diagram, or help students to get familiar with the data set first? Finally, the lecture is rather dry without enough examples

This course is lacking a LOT. The presentations are uninspired and read directly off a script, and have no helpful explanatory background. The lectures themselves are WAY dumbed down compared to the actual quizzes - I struggle to see how anyone who's a true SQL beginner could pass a lot of these quizzes with information from the lectures only.

This instructor doesn't do a very good job elaborating on why we code this way. I had to take another instructor's sql class to finish the assignments. She gave me the impression that she read from a script entire time instead of talking about things that she really understands. But I do like the coding assignments which are very helpful.

The lack of ability to follow along due to no common software or commands was extremely irritating. The brilliant idea that I should investigate one online and figure out how it works was what I thought I was taking the class for. Why not choose an open source program and focus on the methodologies?

Lectures were very bad. It sounded like she was reading a speech that was written the night before, with grammatical errors and all. Both over-explained simple things, and under explained complex things. I did most of my learning on https://www.sqlitetutorial.net in order to pass the assignments.

the course is completely theoretical and not use MySQL with using the theory you can get help in work but real life database and application is not included in this course so if you want to learn and apply directly you can do that in this course, which decrease the interest in course materials.
The course gives basic elements of SQL, but there is no practice in the course (beside graded assignments), code is shown only in presentation (you cannot copy and and see how it works), and learning SQL without constant practice is nearly impossible. The peer graded assignment is messy.
Course is very theoretical, the teachers just reads presentation with SQL functions, there's no way to actually learn SQL by listening to it. Also she doesn't provide information about essentials of databases, so the beginners may not understand the concept of it.

It is a good conceptual introduction to SQL, but as many other reviews say: it lacks the real hands-on work that teaches you coding skills and good practice in choosing different query strategies.
Overal I am on the fence on whether it was worth the costs..

The mistakes in the presentations and the massive ambiguity in the final assignment were a complete letdown for me. All in all, I did learn everything that was taught, but I wonder how much of that was made possible thanks to my previous experience in IT.

Good course to learn the basics but not worth the price you pay. Until week 3, everything is fine, but week 4 is a disaster. The final assignment is very confusing and sometimes it is hard to know what you are being asked. Not recommended.

The course has no transcript for review. And the system of SQL exercise is also wrong when you are using “WHERE” Clause and “=” signal. Because of the mistakes of system I even can not make any progress. Please check.

The course went fine up until the final assignment. It was very irritating to do, because of the incomplete database, broken correlations, different tables stating different things, which should've been the same, etc.

The instructor spent too much time on unnecessary and self-explaining topics, and on the other hand failed to explain some important details. I ended up skipping much of the course and googled a lot by myself.

Decent introduction. I recommend https://mode.com/sql-tutorial for a better introduction to SQL.
Assignments are very badly designed. Also the questions in the final assignment are unnecessarily repetitive!

The lectures were not easy to comprehend for a computer language. Though the course mentions it is a beginner-level course, the lecturer jumps to a certain part where there is a learning curve expected.
автор: Ligeng X•
A little too easy, not challenging at all, given this is a beginner level class, I'll give it two stars. You could finish the whole course on Saturday if you get up early plus Sunday if you do not.
I wish that the instructor used examples that mirrored the type of questions in the coding exams. We did not cover all the material in the coding exam.
автор: Darren R•
The structure and guidance provided on the final assignment was very poor, resulting in far more time required to complete than expected.
автор: Riccardo B•
too much theory, I needed something more 'pratical' that allowed me to start using and write code and not see a lot of slide with code

1.Very basic course.
2. Assignments level does not match with training level.
3. Need to provide class which includes query writing.
